| Initiative Description: one math class (ACTB), 5-min physical activity breaks were implemented and occurred immediately after the math message and immediately prior to the beginning of work time; student to roll a dice three times, based on the dice numbers rolled, all students would have to perform the corresponding activities for 30 s each; STAB teacher removed all chairs at the start of the school year and replaced the standard desk chairs with appropriate-sized stability balls so that all students could sit on the ball such that the student’s back was straight, hips and knees bent at 90 degrees, and feet were able to lay flat on the floor and did not incorporate any other physical activity Study results: The use of stability balls resulted in greater standardized test performance in comparsion to both control and physical activity break groups.
